Wordpress (Woocommerce extension) - Create new order programmatically

Here's how I programmatically create my orders. I largely followed WC_Checkout::create_order() from @pavel's suggestion above. This is directly from a plugin I'm writing so you'll have to adjust where the source data comes form.

// build order data$order_data = array(    'post_name'     => 'order-' . date_format($order_date, 'M-d-Y-hi-a'), //'order-jun-19-2014-0648-pm'    'post_type'     => 'shop_order',    'post_title'    => 'Order – ' . date_format($order_date, 'F d, Y @ h:i A'), //'June 19, 2014 @ 07:19 PM'    'post_status'   => 'wc-completed',    'ping_status'   => 'closed',    'post_excerpt'  => $order->note,    'post_author'   => $account->user_id,    'post_password' => uniqid( 'order_' ),   // Protects the post just in case    'post_date'     => date_format($order_date, 'Y-m-d H:i:s e'), //'order-jun-19-2014-0648-pm'    'comment_status' => 'open');// create order$order_id = wp_insert_post( $order_data, true );if ( is_wp_error( $order_id ) ) {    $order->errors = $order_id;} else {    $order->imported = true;    // add a bunch of meta data    add_post_meta($order_id, 'transaction_id', $order->transaction_id, true);     add_post_meta($order_id, '_payment_method_title', 'Import', true);    add_post_meta($order_id, '_order_total', $order->gross, true);    add_post_meta($order_id, '_customer_user', $account->user_id, true);    add_post_meta($order_id, '_completed_date', date_format( $order_date, 'Y-m-d H:i:s e'), true);    add_post_meta($order_id, '_order_currency', $order->currency, true);    add_post_meta($order_id, '_paid_date', date_format( $order_date, 'Y-m-d H:i:s e'), true);    // billing info    add_post_meta($order_id, '_billing_address_1', $order->address_line_1, true);    add_post_meta($order_id, '_billing_address_2', $order->address_line_2, true);    add_post_meta($order_id, '_billing_city', $order->city, true);    add_post_meta($order_id, '_billing_state', $order->state, true);    add_post_meta($order_id, '_billing_postcode', $order->zip, true);    add_post_meta($order_id, '_billing_country', $order->country, true);    add_post_meta($order_id, '_billing_email', $order->from_email, true);    add_post_meta($order_id, '_billing_first_name', $order->first_name, true);    add_post_meta($order_id, '_billing_last_name', $order->last_name, true);    add_post_meta($order_id, '_billing_phone', $order->phone, true);    // get product by item_id    $product = get_product_by_sku( $order->item_id );    if( $product ) {        // add item        $item_id = wc_add_order_item( $order_id, array(            'order_item_name'       => $product->get_title(),            'order_item_type'       => 'line_item'        ) );        if ( $item_id ) {            // add item meta data            wc_add_order_item_meta( $item_id, '_qty', 1 );             wc_add_order_item_meta( $item_id, '_tax_class', $product->get_tax_class() );            wc_add_order_item_meta( $item_id, '_product_id', $product->ID );            wc_add_order_item_meta( $item_id, '_variation_id', '' );            wc_add_order_item_meta( $item_id, '_line_subtotal', wc_format_decimal( $order->gross ) );            wc_add_order_item_meta( $item_id, '_line_total', wc_format_decimal( $order->gross ) );            wc_add_order_item_meta( $item_id, '_line_tax', wc_format_decimal( 0 ) );            wc_add_order_item_meta( $item_id, '_line_subtotal_tax', wc_format_decimal( 0 ) );        }        // set order status as completed        wp_set_object_terms( $order_id, 'completed', 'shop_order_status' );        // if downloadable         if( $product->is_downloadable() ) {            // add downloadable permission for each file            $download_files = $product->get_files();            foreach ( $download_files as $download_id => $file ) {                wc_downloadable_file_permission( $download_id, $product->id, new WC_Order( $order_id ) );            }        }    } else {        $order->errors = 'Product SKU (' . $order->$item_id . ') not found.';    }}function get_product_by_sku( $sku ) {    global $wpdb;    $product_id = $wpdb->get_var( $wpdb->prepare( "SELECT post_id FROM $wpdb->postmeta WHERE meta_key='_sku' AND meta_value='%s' LIMIT 1", $sku ) );    if ( $product_id ) return new WC_Product( $product_id );    return null;}

Order Class

The is the interim class I use to store the orders before importing into WordPress / WooCommerce.

class ImportOrder{    // public vars    public $date;    public $time;    public $time_zone;    public $first_name;    public $middle_name;    public $last_name;    public $type;    public $status;    public $currency;    public $gross;    public $fee;    public $net;    public $note;    public $to_email;    public $from_email;    public $transaction_id;    public $counterparty_status;    public $address_status;    public $item_title;    public $item_id;    public $address_line_1;    public $address_line_2;    public $city;    public $state;    public $zip;    public $country;    public $phone;    public $imported;    public $errors;}

Add Order

The data here is imported from a PayPal CSV download of historical transactions. The $row variable represents one row in the CSV. You can adjust this to suit your needs.

function add_import_order( $row ) {    // create new order    $order = new ImportOrder();    // done this before?    $order->exists = order_exists( $row[PayPalCols::TRANSACTION_ID] );    // add a bunch of fields    $order->date = $row[PayPalCols::DATE];    $order->time = $row[PayPalCols::TIME];    $order->time_zone = $row[PayPalCols::TIME_ZONE];    $order->type = $row[PayPalCols::TYPE];    $order->status = $row[PayPalCols::STATUS];    $order->currency = $row[PayPalCols::CURRENCY];    $order->gross = $row[PayPalCols::GROSS];    $order->fee = $row[PayPalCols::FEE];    $order->net = $row[PayPalCols::NET];    $order->note = $row[PayPalCols::NOTE];    $order->from_email = $row[PayPalCols::FROM_EMAIL];    $order->to_email = $row[PayPalCols::TO_EMAIL];    $order->transaction_id = $row[PayPalCols::TRANSACTION_ID];    $order->counterparty_status = $row[PayPalCols::COUNTERPARTY_STATUS];    $order->address_status = $row[PayPalCols::ADDRESS_STATUS];    $order->item_title = $row[PayPalCols::ITEM_TITLE];    $order->item_id = $row[PayPalCols::ITEM_ID];    $order->address_line_1 = utf8_encode( $row[PayPalCols::ADDRESS_LINE_1] );    $order->address_line_2 = utf8_encode( $row[PayPalCols::ADDRESS_LINE_2] );    $order->city = utf8_encode( $row[PayPalCols::TOWN_CITY] );    $order->state = utf8_encode( $row[PayPalCols::STATE] );    $order->zip = utf8_encode( $row[PayPalCols::ZIP] );    $order->country = utf8_encode( $row[PayPalCols::COUNTRY] );    $order->phone = utf8_encode( $row[PayPalCols::PHONE] );    return $order;}

For creating New order, You will have to create Object of WC_Order, If you working outside WooCommerce or in function.php then, First Define Global $woocommerce variable.

So, There will be just 2 line of Code.

global $woocommerce;$order = new WC_Order( $order_id );

Hope, It will help You.

As of WooCommerce 2.2 (or maybe 2.1 I'm not 100% sure) there is now a function specifically designed for this.

wc_create_order( $args = array() )

with the following default arguments.

$default_args = array(    'status'        => '',    'customer_id'   => null,    'customer_note' => null,    'order_id'      => 0);

You can see the whole function in the includes/wc-core-functions.php file.
